Professional rainwater filters - optimum cleaning for any application

To save space, our internal filters are integrated in the tank. The external filters are installed in a robust plastic shaft. Due to the larger pipe cross-sections, they are also suited to particularly large roof areas or can be used for infiltration and pond systems, for example.
